This paper quantitatively analyzes the German Renewable Energy Act reform (EEG-reform) in 2012. Results imply that the reform contributes to an expansion of biogas electricity generation compared to former versions of the legislation, and thus contributes to substitution of fossil fuels. By restricting the share of green maize input, the production of green maize is reduced and the crop-mix is diversified. However, since maize provides the highest energy output per area, total land requirement for biogas production increases.
